Unsettling Dreams . . .

For three nights in a row I've been plagued with unsettling dreams.  I don't remember any from a couple of nights ago, night before last I dreamed my brother was coming here and for some reason I kept looking for something in the trunks of other people's cars.  Last night I dreamed Mother and I were driving and first we were approaching a very narrow section of highway under construction and I was barely in front of an 18 wheeler and I had to scoot in front of him or he'd push me into the other lane of traffic, so I did that narrowly missing the vehicle in front of me, and the 18 wheeler narrowly missed me, then suddenly I 'awoke' in the dream, I'd been driving asleep, and was on the top of a very high, old bridge.  It appeared at first we'd wandered onto a road that was demolished from the top of the bridge down, but turned out there was more road going down, and it led to a dead end.  On the right was an old metal factory.  I was saying I'd fallen asleep and I didn't know where we were, Mother told me to drive into the factory's parking lot and we'd ask where we were.  At some point I'd gotten out of the car, I guess to find someone, and for whatever reason Mother got behind the wheel and started moving the car.  For whatever reason we had the puppies and other dogs in the car and one of the puppies had gotten out and mother yelled that she'd just run over one of the puppies.  I looked over and it lay on the parking lot and she ran over it again (it kills me to type this).  It wasn't dead so I picked it up to comfort it as it died and I was very very angry with Mother for letting it out and thankfully I woke up.
